FIG. 1 illustrates an electronic device according to an embodiment of the disclosure.

Referring to FIG. 1, the electronic device 101 may include a display 110 and a housing (or a main body) 120.

The display 110 according to various embodiments may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diodes (OLED) display, a microelectromechanical systems (MEMS) display, or electronic paper. For example, the display 110 may display various types of contents (e.g., text, images, videos, icons, and/or symbols) to a user. The display 110 may include a touch screen and may receive, for example, a touch, a gesture, a proximity, or a hovering input using an electronic pen or a part of the user's body.

The housing (or the main body) 120 according to various embodiments may have the display 110 mounted therein. The housing 120 may contain various components for driving the electronic device 101.

According to various embodiments, the housing 120 may contain a main circuit board 130, a battery 140, a battery protection module 150, and a flexible printed circuit board 180.

The main circuit board 130 according to various embodiments may have various elements mounted thereon and required for operations of the electronic device 101. For example, the main circuit board 130 may have a processor, a memory, a communication chip, or a sensor mounted thereon. The main circuit board 130 may include a power supply point. The power supply point may be a point to which the power of the battery 140 is supplied through the flexible printed circuit board 180. The main circuit board 130 may supply the power transferred through the power supply point to the mounted or connected elements.

The battery 140 according to various embodiments may store electrical energy depending on chemical properties. The battery 140 may supply power to the main circuit board 130 through the battery protection module 150 and the flexible printed circuit board 180. For example, the battery 140 may be implemented in a Li-ion type.

The battery protection module 150 according to various embodiments may prevent overcharge or over discharge of the battery 140 and may protect the battery 140 from over-current. For example, the battery protection module 150 may be a protection circuit module (PCM) or a protection circuit board (PCB). According to various embodiments, the battery protection module 150 may be surrounded by a protective holder (or a battery holder) (e.g., a PCM holder).

The flexible printed circuit board 180 may make a connection between the battery protection module 150 and the main circuit board 130. The flexible printed circuit board 180 may transfer power from the battery 140 to the power supply point of the main circuit board 130. A first end portion of the flexible printed circuit board 180 may be connected to the battery protection module 150. A second end portion of the flexible printed circuit board 180 may be connected to the power supply point of the main circuit board 130.

According to various embodiments, at least part of the flexible printed circuit board 180 may be bent in the shape of “U”. For example, the flexible printed circuit board 180 may bent in the shape of “U” after extending from the first end portion by a predetermined length in a lateral outward direction of the electronic device 101 (a perpendicular direction to the direction in which the battery protection module 150 faces the main circuit board 130). The flexible printed circuit board 180, after being bent in the shape of “U”, may be disposed to overlap the battery protection module 150 (refer to FIGS. 3 to 6).

FIG. 2 illustrates components around a battery according to an embodiment of the disclosure.

Referring to FIG. 2, the battery 140 may store electrical energy depending on chemical properties. For example, the battery (or the battery structure) 140 may include a positive electrode plate, a negative electrode plate, a separator, a jelly roll, and a pouch (or a battery pouch). The positive electrode plate and the negative electrode plate may be separated from each other by the separator. The positive electrode plate, the negative electrode plate, and the separator may form the jelly roll, and the jelly roll may be sealed with the pouch (e.g., polypropylene (PP)+nylon+Al).

The battery protection module (or the protection module) 150 according to various embodiments may be mounted on one side surface of the battery 140 (a side surface adjacent to the main circuit board 130). The battery protection module 150 may include a substrate, a protection integrated circuit (IC), a first tab 151, and a second tab 152 (refer to FIGS. 7A and 7B). The first tab 151 may be connected to a first electrode (the positive electrode plate) (e.g., Al) of the battery 140, and the second tab 152 may be connected to a second electrode (the negative electrode plate) (e.g., Cu) of the battery 140.

According to various embodiments, the battery protection module 150 may be surrounded by a protective holder (or a battery holder) 155. When the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact) in a state in which the protective holder 155 is not present, the battery protection module 150 may be broken, and the jelly roll may penetrate through the pouch and may be exposed outside the battery 140. In contrast, when the jelly roll in the battery 140 moves in a state in which the protective holder 155 is present, the protective holder 155 may support the jelly roll, thereby preventing the pouch of the battery 140 from bursting.

The flexible printed circuit board 180 may be connected to one side surface of the battery protection module 150. The flexible printed circuit board 180 may be connected to a side surface of the battery protection module 150 rather than the surface of the battery protection module 150 that faces the main circuit board 130 (the surface on which the first tab 151 and the second tab 152 are mounted).

According to an embodiment, the flexible printed circuit board 180 may have a planar form, in a state 180 a of not being combined with the battery protection module 150. The flexible printed circuit board 180 may be at least partially bent in the shape of “U” when combined with the battery protection module 150. The flexible printed circuit board 180 may include a first portion connected to the battery protection module 150, a second portion bent from the first portion in the shape of “U”, a third portion that extends from the second portion and that is stacked over the battery protection module 150, a fourth portion extending toward the main circuit board 130 from the third portion, and a connector connected to the main circuit board 130 (refer to FIG. 4).

According to various embodiments, part of the flexible printed circuit board 180 may be exposed outside the protective holder 155. The protective holder 155 may include an opening or a recess in a region adjacent to the flexible printed circuit board 180. The flexible printed circuit board 180 may extend outside the protective holder 155 through the opening or the recess.

FIG. 3 illustrates attachment of a covering tape according to an embodiment of the disclosure.

Referring to FIG. 3, the battery protection module 150 and the protective holder 155, which are connected to the battery 140, may be covered by the covering tape 310. The covering tape 310 may cover the side surface of the battery 140 to which the battery protection module 150 is connected, part of the upper surface of the battery 140 that is adjacent to the side surface, and part of the lower surface of the battery 140 that is opposite to the upper surface. The covering tape 310 may prevent a movement of the protective holder 155, thereby maintaining the forms of the battery protection module 150 and the protective holder 155 and the gap therebetween.

According to an embodiment, the flexible printed circuit board 180 may extend in a direction toward a side surface not covered by the covering tape 310, and part of the flexible printed circuit board 180 may be disposed over the covering tape 310. For example, the portion of the flexible printed circuit board 180 that extends from the U-shaped portion may be disposed over the covering tape 310 attached to the protective holder 155.

FIG. 4 illustrates the form of the flexible printed circuit board according to an embodiment of the disclosure.

Referring to FIG. 4, the flexible printed circuit board 180 may include a first portion 410, a second portion 420, a third portion 430, a fourth portion 440, and a connector 450.

The first portion 410 (or the battery protection module connection portion) according to various embodiments may be a portion that is connected to the battery protection module 150. The first portion 410 may extend from the battery protection module 150 in a direction (hereinafter, referred to as the second direction (e.g., −x direction)) that is perpendicular to the direction toward the main circuit board 130 (or the direction in which the first tab 151 and the second tab 152 protrude) (hereinafter, referred to as the first direction (e.g., −y direction)). The second direction may be a direction toward the outside from the interior of the electronic device 101. The first portion 410 may be disposed on the same layer (the same plane) as the battery protection module 150.

According to various embodiments, the width of the first portion 410 may be the same as, or similar to, the width of a connecting portion of the battery protection module 150 (e.g., a connecting portion 710 a of FIG. 7A). In an embodiment, one side surface of the battery protection module 150 may have a greater width than the other portion of the battery protection module 150 (refer to FIGS. 7A and 7B). The electrical resistance of a conductor may be reduced with an increase in the width of the first portion 410.

The second portion 420 (or the curved portion) according to various embodiments may be a portion that is formed so as to be bent from the first portion 410 in the shape of “U” in a direction (e.g., +z direction) that is perpendicular to the first direction and the second direction. The curvature of the second portion 420 may be determined depending on material characteristics. The first portion 410 and the third portion 430 may form different layers by the second portion 420.

The third portion 430 (or the first extension) according to various embodiments may be a portion that extends from the second portion 420 in a third direction (e.g., +x direction) that is opposite to the second direction. The third portion 430 may be disposed on a different layer (a different plane) from the first portion 410 because the second portion 420 is bent in the shape of “U”. Furthermore, the third portion 430 may be disposed on a different layer (a different plane) from the battery protection module 150. The third portion 430 may be disposed on an upper portion (an outer surface) of the battery protection module 150.

According to various embodiments, the third portion 430 may have a straight line form. The third portion 430 may extend parallel to the first portion 410 along the upper surface of the battery protection module 150 (or the upper surface of the protective holder 155). With an increase in the length of the third portion 430, the third portion 430 may better resist stress caused by an external impact (refer to FIG. 5).

The fourth portion 440 (or the second extension) according to various embodiments may be a portion that extends from the third portion 430 in the first direction (e.g., −y direction) toward the main circuit board 130. The fourth portion 440 may be disposed on the same layer (the same plane) as the third portion 430. The fourth portion 440, together with the third portion 430, may be formed in the shape of “L”. The fourth portion 440 may be implemented in the form of a straight line or a curve. The fourth portion 440 may be implemented in various forms depending on the position of the power supply point of the main circuit board 130 and the form of the main circuit board 130.

The connector 450 according to various embodiments may be disposed on an end portion of the fourth portion 440. The connector 450 may be connected to a different connector of the main circuit board 130 (e.g., a connector paired with the connector 450). According to an embodiment, the flexible printed circuit board 180 may include, on an opposite surface to the surface on which the connector 450 is disposed, a pad implemented with a metallic material (e.g., Cu). According to various embodiments, the connector 450 may be in various forms. For example, the connector 450 may be implemented in a contact pad form. According to another embodiment, the connector 450 may be implemented with an electric wire connected through soldering.

According to various embodiments, the fourth portion 440 may include a V or W bending portion 441 on at least part thereof. The V or W bending portion 441 may improve a buffer function of the fourth portion 440 when the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact).

Although FIG. 4 illustrates the example that the fourth portion 440 includes the V or W bending portion 441, the disclosure is not limited thereto. For example, the flexible printed circuit board 180 may include a V or W bending portion on the first portion 410 or the third portion 430.

FIG. 5 illustrates a deformed form depending on a width of a flexible printed circuit board and stress according to an embodiment of the disclosure.

Referring to FIG. 5, the flexible printed circuit board 180 may include the first portion 410, the second portion 420, the third portion 430, the fourth portion 440, and the connector 450.

The first portion 410 may be disposed inside the protective holder 155, and the third portion 430, the fourth portion 440, and the connector 450 may be disposed outside the protective holder 155.

According to various embodiments, the first portion 410, the second portion 420, and the third portion 430 may have a first width A. The first width A may be determined depending on the width of the connecting portion of the battery protection module 150 (e.g., the connecting portion 710 a of FIG. 7A) to which the first portion 410 is connected. The first width A may be smaller than the width of the battery protection module 150.

The fourth portion 440 may have a second width B greater than the first width A. With an increase in the second width B, electrical resistance (e.g., direct current (DC) resistance) that occurs in the fourth portion 440 may be reduced. The fourth portion 440 may include the V or W bending portion 441.

When the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact), the first to fourth portions 410 to 440 may deform, and the flexible printed circuit board 180 may be elongated in an up/down direction (Y-axis direction). Accordingly, the flexible printed circuit board 180 may be prevented from being separated from the main circuit board 130 or the battery protection module 150.

When the first to fourth portions 410 to 440 deform, the first to fourth portions 410 to 440 may be subjected to stress induced by the deformation. The first portion 410, the second portion 420, and the third portion 430 may be subjected to a larger stress than the fourth portion 440. The fourth portion 440 may be subjected to a smaller stress than the first portion 410, the second portion 420, and the third portion 430.

When the electronic device 101 is subjected to a drop impact, the angle “a” between the third portion 430 and the straight line x′ parallel to the X axis may be increased. With an increase in the length of the third portion 430, the angle “a” capable of coping with a movement of the battery 140 may be increased, and an effective response to the external impact may be made.

When the electronic device 101 is subjected to a drop impact, the fourth portion 440 may be elongated by the V or W bending portion 441 of the fourth portion 440. Accordingly, an effective response to the external impact may be made.

FIG. 6 illustrates a form of a flexible printed circuit board over a protective holder according to an embodiment of the disclosure.

Referring to FIG. 6, the flexible printed circuit board 601 (e.g., the flexible printed circuit board 180) may include a first portion (not illustrated) (e.g., the first portion 410), a second portion 620 (e.g., the second portion 420), a third portion 630 (e.g., the third portion 430), a fourth portion 640 (e.g., the fourth portion 440), and a connector 650 (e.g., the connector 450).

The third portion 630 of the flexible printed circuit board 601 may be disposed over the protective holder 155. The third portion 630 may extend from the second portion 620 having a curved form along an upper surface of the protective holder 155.

According to various embodiments, the length of the third portion 630 may be the same as, or similar to, the length of the protective holder 155. The width of the third portion 630 may be equal to, or smaller than, the width of the protective holder 155.

According to various embodiments, the third portion 630 may be longer than the fourth portion 640. With an increase in the length of the third portion 630, the third portion 630 may effectively cope with a movement of the battery 140, thereby preventing damage caused by an impact.

According to various embodiments, the third portion 630 may include a V or W bending portion 631 on at least part thereof. The V or W bending portion 631 may improve a buffer function of the third portion 630 when the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact).

Although FIG. 6 illustrates the example that the third portion 630 includes one V or W bending portion 631, the disclosure is not limited thereto. For example, a plurality of V or W bending portions 631 may be disposed at specified intervals.

FIG. 7A illustrates a battery protection module according to an embodiment of the disclosure.

Referring to FIG. 7A, the battery protection module 150 may include a substrate 710, protection ICs 720, the first tab 151, and the second tab 152. The substrate 710 may have the protection ICs 720, the first tab 151, and the second tab 152 mounted thereon and may electrically connect the protection ICs 720, the first tab 151, and the second tab 152. The protection ICs 720 may prevent overcharge or over discharge of the battery 140 and may protect the battery 140 from over-current. The first tab 151 may be connected to the first electrode (the positive electrode plate) of the battery 140, and the second tab 152 may be connected to the second electrode (the negative electrode plate) of the battery 140.

According to various embodiments, the substrate 710 may include, on a side surface thereof (a surface rather than the surface facing the main circuit board 130 or the battery 140), the connecting portion 710 a connected to the flexible printed circuit board 180.

According to an embodiment, the width T1 of the connecting portion 710 a may be greater than the width T2 of the other region of the substrate 710. The width of the first portion 410 of the flexible printed circuit board 180 connected to the connecting portion 710 a may be determined based on the width T1 of the connecting portion 710 a. With an increase in the width T1 of the connecting portion 710 a, electrical resistance in the first to third portions 410, 420, and 430 of the flexible printed circuit board 180 may be reduced. According to various embodiments, the connecting portion 710 a may be disposed over a partition between the main circuit board 130 and the battery 140 (refer to FIG. 8).

FIG. 7B is a sectional view of a substrate included in a battery protection module according to an embodiment of the disclosure.

Referring to FIG. 7B, the substrate 710 may include a fixed region 711 and a flexible region 712.

The fixed region 711 according to various embodiments may be a region in which pre-pregs (PPGs) 711 a and base films 711 b (containing Cu) are alternately stacked on each other. The fixed region 711 may have the protection ICs 720 mounted thereon.

The flexible region 712 according to various embodiments may be a region from which the pre-pregs (PPGs) 711 a are at least partially removed. The flexible region 712 may include coverlay films 712 a with which the base films 711 b (containing Cu) are coated. The flexible region 712 may have flexibility due to the removal of the pre-pregs (PPGs) 711 a. The flexible region 712 may include a connector 712 b for connecting the flexible printed circuit board 180.

FIG. 8 is a sectional view of components around a main circuit board and a battery according to an embodiment of the disclosure.

Referring to FIG. 8, the electronic device 101 may include a battery seating area 810 on which the battery 140 is seated.

The battery seating area 810 according to various embodiments may include a battery partition 820 for separating the battery 140 from the main circuit board 130. The battery partition 820 may be disposed to have a specified gap with the battery 140 and may therefore cope with a movement of the battery 140.

According to various embodiments, the battery partition 820 may have a relatively small height in a region adjacent to the connecting portion 710 a of the battery protection module 150. The connecting portion 710 a of the battery protection module 150 may be a portion to which the flexible printed circuit board 180 is connected. The connecting portion 710 a of the battery protection module 150 may have a width greater than the width of the other portion of the battery protection module 150 to ensure the width of the flexible printed circuit board 180.

The connecting portion 710 a of the battery protection module 150 may be disposed over the battery partition 820 to have a specified gap with the battery partition 820 and cover the battery partition 820 when viewed from above.

The flexible printed circuit board 180 may include a V or W bending portion over the main circuit board 130. When the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact), the V or W bending portion allows the flexible printed circuit board 180 to be elongated, thereby performing a buffer function.

FIG. 9A illustrates an example of a protective holder according to an embodiment of the disclosure.

Referring to FIG. 9A, the battery protection module 150 may be surrounded by a protective holder 910 (e.g., the protective holder 155). When the jelly roll in the battery 140 moves (e.g., when the electronic device 101 is subjected to a drop impact), the protective holder 910 may prevent the pouch of the battery 140 from bursting.

According to an embodiment, the protective holder 910 may include, in a side surface thereof (a surface not facing the main circuit board 130 or the battery 140), an opening 911 a through which the flexible printed circuit board 180 passes. The first portion 410 or the second portion 420 of the flexible printed circuit board 180 may be connected to the outside of the protective holder 910 through the opening 911 a. The third portion 430 of the flexible printed circuit board 180 may be disposed over the protective holder 910.

When part of the flexible printed circuit board 180 is disposed outside the protective holder 910, an extension range may be widened depending on an external impact, and the flexible printed circuit board 180 may more efficiently resist stress.

FIG. 9B illustrates another example of a protective holder according to an embodiment of the disclosure.

Referring to FIG. 9B, a protective holder 920 (e.g., the protective holder 155) may not include, in a side surface thereof (a surface not facing the main circuit board 130 or the battery 140), a separate opening though which the flexible printed circuit board 180 passes.

The first portion 410 or the second portion 420 of the flexible printed circuit board 180 may be disposed inside the protective holder 920. The third portion 430 of the flexible printed circuit board 180 may be connected to the outside of the protective holder 920 through an opening formed in a surface of the protective holder 920 that faces the main circuit board 130.
